"(a) Study.—The Administrator of the Environmental Protection Agency and the Secretary of Transportation, in consultation with the Secretary of Defense, shall commence a study and investigation of the testing of uninstalled aircraft engines in enclosed test cells that shall address at a minimum the following issues and such other issues as they shall deem appropriate—

"(1) whether technologies exist to control some or all emissions of oxides of nitrogen from test cells;

"(2) the effectiveness of such technologies;

"(3) the cost of implementing such technologies;

"(4) whether such technologies affect the safety, design, structure, operation, or performance of aircraft engines;

"(5) whether such technologies impair the effectiveness and accuracy of aircraft engine safety design, and performance tests conducted in test cells; and
